Controlled free-induction decay in the extreme ultraviolet
Samuel Bengtsson, Esben W. Larsen, David Kroon +8
Coherent sources of attosecond extreme ultraviolet (XUV) radiation present many challenges if their full potential is to be realized. While many applications benefit from the broad…
Introduction to attosecond time-delays in photoionization
J. M. Dahlström, A. L'Huillier, A. Maquet
This tutorial presents an introduction to the interaction of light and matter on the attosecond timescale. Our aim is to detail the theoretical description of ultra-short time-dela…
Theory of attosecond delays in laser-assisted photoionization
J. M. Dahlström, D. Guénot, K. Klünder +5
We study the temporal aspects of laser-assisted extreme ultraviolet (XUV) photoionization using attosecond pulses of harmonic radiation. The aim of this paper is to establish the g…
Phase Measurement of Resonant Two-Photon Ionization in Helium
M. Swoboda, T. Fordell, K. Klünder +7
We study resonant two-color two-photon ionization of Helium via the 1s3p 1P1 state. The first color is the 15th harmonic of a tunable titanium sapphire laser, while the second colo…
Intensity Dependence of Laser-Assisted Attosecond Photoionization Spectra
M. Swoboda, J. M. Dahlstrom, T. Ruchon +4
We study experimentally the influence of the intensity of the infrared (IR) probe field on attosecond pulse train (APT) phase measurements performed with the RABITT method (Reconst…
Spectral signature of short attosecond pulse trains
E. Mansten, J. M. Dahlstrom, J. Mauritsson +10
We report experimental measurements of high-order harmonic spectra generated in Ar using a carrier-envelope-offset (CEO) stabilized 12 fs, 800nm laser field and a fraction (less th…
